How did this strategy fare during the last couple days though? Wouldn't weeks or months of profit have been wiped out? Though I guess if it's done for a long enough time it's probably ok

Yeah I’d built up a sufficient buffer, and suspected a correction was coming as the VIX and S&P have been rising together for the last few days. I bought puts 2 days ago instead of selling them. Even if I hadn’t, the last few days would have taken out 25% of my strategy gains YTD. However as a put seller I’d have rolled them down and out, repeatedly, until they expire OTM.

If you lack the cojones for such a mad strategy haha, you can always sell put credit spreads to define your risk at the cost of reducing your return.
